Title: Working on an elm and erc longbow
Post by: GB on November 09, 2014, 03:19:37 am

I'm doing the final tillering on my first ERC bow.  I found a nice board that I was able to get a mostly heartwood, knot free slat from and backed it with 1/8" thick edge grained red elm.  It's 68" long, 1 5/8" at the fades and 45#@ my 27" draw.  I glued in 3" of reflex and it's holding 2 1/4" of it after putting 50 arrows thru it.  Thinking that I might have the very outer limbs a little too stiff yet.  Any body else seeing that?
Thanks-
Greg

Nice job man.  The unbraced profile looks real nice.

Thanks for the encouraging words, guys.  Guess I'll do the final sanding and shoot it a little more.  Getting antsy to finish it now. :)

Since you have reached your draw length, further tillering will only reduce the draw weight and make a longer draw possible-neither of which would help you.

If you needed to go  to 28", the outer limbs could bend more, but, as I said...

It's the lower limb that could bend a bit more in the outer limb but I agree with Jim, best to just leave it

Thanks for the advice Jim and Marc.  I'm happy with the way it shoots so I guess I'll just leave it as is.  I really liked the backed ERC bow that you made for the article in PA magazine awhile back, Marc.  In fact, that's what prompted me to give ERC a try.
